As water-soluble compounds, they are preferably of interest for dyeing and printing textile materials containing hydroxyl groups and textile materials containing nitrogen, in particular textile materials of natural and regenerated cellulose, and furthermore of wool, silk and synthetic polyamide and polyurethane fibres.

The products are particularly suitable as reactive dyestuffs for dyeing cellulose materials by the techniques known for this dyeing.

The formulae indicated are those of the free acids. In general, the alkali metal salts, which are obtained during the synthesis, and in particular the sodium salts, are employed for dyeing.

EXAMPLE 1

17.7 g of 1-amino-4-(3'-amino-phenylamino)-anthraquinone-2,4'-disulphonic acid are dissolved, at pH 5, in 400 ml of water. After cooling the solution to 0°-5°, 3.1 ml of cyanuric fluoride are slowly added dropwise and the pH value is kept at 4.5 with 2 N sodium carbonate solution. After subsequently stirring the mixture for a short time, a solution, adjusted to pH 6, of 12.1 g of 2-(4'-amino-2'-ureido-phenylazo)-benzenesulphonic acid in 180 ml of water is added to the anthraquinone component. The pH value is further kept at 5.8-6.0 with sodium carbonate solution and the temperature is allowed to rise to 20°. After the reaction had ended, the dyestuff is salted out with 100 g of sodium chloride. The product which has precipitated is filtered off, washed with 15% strength sodium chloride solution and, after making into a paste with 10 ml of 5% strength buffer solution of pH 6, is dried at 60° in a circulating air oven. The dyestuff corresponds to the formula ##STR25##

Dyeing instructions

50 g of cotton hanks are dyed in 1 liter of a dye liquor, containing 1.5 g of the above dyestuff, by heating the liquor to 40° in the course of 30 minutes, adding 50 g of sodium sulphate in several portions, then adding 20 g of sodium carbonate and treating the hanks at this temperature for 60 minutes. After rinsing, soaping at the boil and drying, a dyeing is obtained, in a somewhat yellowish-tinged green shade, which is very fast to light, wet processing and chlorine.

EXAMPLE 2

14.7 g of 1-amino-4-(4'-amino-phenylamino)-anthraquinone-2,3'-disulphonic acid are dissolved in 350 ml of water, under neutral conditions. The solution is cooled to 0°-5° and adjusted to pH 4.5, and 3.2 ml of cyanuric fluoride are immediately added dropwise in the course of 10 minutes. The pH value of the solution is kept at 4.2-4.7 with 1 N sodium carbonate solution. The mixture is then stirred under the same conditions for 20 minutes.

A neutralised solution of 12.5 g of 2-(4'-amino-2'-ureido-phenylazo)-benzene-1,4-disulphonic acid in 300 ml of water is added dropwise to the resulting solution of the difluorotriazinylanthraquinone dyestuff, and the pH value of the reaction mixture is kept at 6.0-6.5 with 1 N sodium carbonate. After subsequently stirring the mixture for 8 hours, the temperature is allowed to rise gradually to 20° overnight and the dyestuff is then salted out with 8% of sodium chloride. It is filtered off, washed with 10% strength sodium chloride solution and dried at 40° in vacuo.

On cotton, the dyestuff of the formula ##STR26## gives, from a long liquor at 40° in accordance with the dyeing process of Example 1, yelowish-tinged green dyeings with good fastness to light and wet processing.

EXAMPLE 3

10.0 g of 1-amino-4-(4'-amino-phenylamino)-anthraquinone-2,3'-disulphonic acid are reacted with 2.0 ml of cyanuric fluoride at pH 4.2-4.7 and at 0°-5° in the manner described in Example 2. A solution, adjusted to pH 6.5, of 9.6 g of 3-(2'-acetylamino-4'-amino-phenylazo)-naphthalene-1,5-disulphonic acid in 200 ml of water is added slowly to the resulting solution at 0°-5°. The pH value of the reaction mixture is kept at 5.5-6.0. The temperature is now allowed to rise gradually form 0°-5° to 10°-12° in the course of 20 hours. The reaction has then ended. The dyestuff is salted out of the resulting green solution by adding 10% of sodium chloride at 20°, filtered off, washed with 10% strength sodium chloride solution and dried at 40° in vacuo. The dyestuff, which corresponds to the formula ##STR27## dyes cotton, from a long liquor at 50°, in yellowish-tinged green shades which are fast to light and wet processing.

EXAMPLE 4

10.0 g of 1-amino-4-(4'-amino-phenylamino)-anthraquinone-2,3'-disulphonic acid are dissolved in 250 ml of water and the solution is adjusted to pH 4.5. After cooling the solution to 0°-5°, 2.0 ml of cyanuric fluoride are added dropwise in the course of 10 minutes and the pH value is kept at 4.2-4.7 with 1 N soda. After subsequently stirring the mixture for half an hour, a solution, adjusted to pH 6 and cooled to 0°-5°, of 10.3 g of 7-(4'-amino-2'-ureido-phenylazo)-naphthalene-1,3,6-trisulphonic acid is added and the pH value of the reaction mixture is kept at 6.0 with 1 N sodium carbonate solution. The mixture is stirred under the conditions indicated for 20 hours, then warmed to 20° and subsequently clarified with 2.5 g of charcoal and 2.5 g of kieselguhr, and the dyestuff is salted out with 10% of sodium chloride. The precipitated dyestuff is filtered off, washed with 10% strength sodium chloride solution and dried at 40° in vacuo. The dyestuff of the formula ##STR28## dyes cotton, from a long liquor at 40°-50° in accordance with the process of Example 1, in yellowish-tinged green shades which are fast to light and wet processing.

If the anthraquinone components indicated in Table I, column II are reacted with cyanuric fluoride and the product is then subjected to a condensation reaction in an analogous manner with the azo components listed in column III, further dyestuffs are obtained which dye cotton, from a long liquor, in the colour shades indicated.

EXAMPLE 26

10.0 g of 1-amino-4-(4'-amino-phenylamino)-anthraquinone-2,3'-disulphonic acid are dissolved in 250 ml of water, under neutral conditions. 2.0 ml of cyanuric fluoride are added dropwise, in the course of 10 minutes, to the solution, which has been adjusted to pH 4.5 and cooled to 0°-5°, and during this addition the pH value is kept at 4.2-4.7 with 1 N sodium carbonate solution. The mixture is then stirred under the same conditions for a further 20 minutes.

A neutralised solution of 10.5 g of 1-(4'-sulphophenyl)-3-carboxy-4-(5"-amino-2"-sulphophenylazo)-5-pyrazolone in 150 ml of water is now allowed to run into the resulting solution of the difluorotriazinylanthraquinone dyestuff at 0°-5°. The pH value is kept at 5.5-6.0 during this condensation stage. When the reaction has almost ended, after 5-6 hours, the temperature is allowed to rise gradually to 20°, the resulting green dyestuff solution is clarified with 2.5 g of active charcoal and 2.5 g of kieselguhr, and 10% of sodium chloride are introduced into the filtrate. The dyestuff which has precipitated is filtered off, washed with sodium chloride solution and dried at 40° in vacuo.

It corresponds to the formula ##STR29## and dyes cotton, from a long liquor at 40° in accordance with the dyeing process indicated in Example 1, in clear, yellowish-tinged green shades. The dyeings have good fastness to light and wet processing.

EXAMPLE 27

9.8 g of 1-amino-4-(3'-amino-phenylamino)-anthraquinone-2,4'-disulphonic acid are dissolved in 150 ml of water. The solution is adjusted to pH 5 and cooled to 0°-5°, and 1.9 ml of cyanuric fluoride are added dropwise in the course of 10 minutes. The pH is kept at 4.5 with 2 N sodium carbonate solution during this addition. After a subsequent stirring time of 15 minutes, a neutralised solution of 11.3 g of 1-(2',5'-dichloro-4'-sulphophenyl)-3-methyl-4-(4"-amino-2"-sulpho-phenylazo)-5-pyrazolone in 110 ml of water is allowed to run in and the pH value is kept at 6 with sodium carbonate solution. The temperature is now allowed to rise to 20° and, after the reaction has ended, the dyestuff is salted out with potassium chloride. The dyestuff, which corresponds to the formula ##STR30## is filtered off, washed with potassium chloride solution and, after adding 10 ml of 5% strength buffer solution (pH=6.0), is dried at 60° in vacuo.

The dyestuff dyes cotton, from a long liquor in accordance with the process described in Example 1, in olive-green shades.

EXAMPLE 28

10.0 g of 1-amino-4-(4'-amino-phenylamino)-anthraquinone-2,3'-disulphonic acid in 250 ml of water are reacted with 2.0 ml of cyanuric fluoride, as described in the preceding Example 26. An equimolar solution, adjusted to pH 9, of the sodium salt of 3-methyl-4-(5'-amino-2'-sulphophenylazo)-5-pyrazolone in 100 ml of water is added dropwise to the difluorotriazinylanthraquinone component and the pH value of the mixture is kept at 6.0 with 1 N sodium carbonate solution. After subsequently stirring the mixture at 0°-5° for 7 hours, the temperature is allowed to rise gradually to 15°-20° in the course of 10 hours. The dyestuff is salted out with sodium chloride, filtered off and washed with 5% strength sodium chloride solution. It is dried at 40° in vacuo.

The dyestuff of the formula ##STR31## dyes cotton, from a long liquor at 40°, in somewhat bluish-tinged green shades which have good fastness to light and wet processing.

Further dyestuffs which dye cotton, from a long liquor, in the shades indicated in Table II are obtained when the anthraquinone components of column II are first subjected to a condensation reaction with cyanuric fluoride and the condensation product is subjected to a further condensation reaction with the azo components of column III.

EXAMPLE 45

9.0 g of 2-(4'-amino-2'-ureido-phenylazo)-benzene-1,4-disulphonic acid are dissolved, at pH 5.8, in 450 ml of water and the solution is cooled to 0°-5°. 2.0 ml of cyanuric fluoride are added dropwise to this solution in the course of 10 minutes, and during this addition the pH is kept between 4.2 and 4.7 with 1 N sodium carbonate solution. In order to bring the reaction to completion, the mixture is subsequently stirred at 0°-5° and at a pH of 4.5 for a further 30 minutes. The resulting solution of the dichlorotriazinylazo dyestuff is added to a solution, adjusted to pH 6, of 10.0 of 1-amino-4-(3'-amino-2'-methyl-phenylamino)-anthraquinone-2,5'-disulphonic acid in 150 ml of water in the course of 30 minutes. During this addition, the temperature is further kept at 0°-5° and the pH value is kept at 5.8-6.0 with sodium carbonate solution. After 6 hours, the green solution is warmed to 20° and subsequently stirred at this temperature and at a pH value of 7 for 2 hours, and the dyestuff is then salted out with 200 g of sodium chloride. The dyestuff of the formula ##STR32## which has precipitated in the form of the sodium salt, is filtered off, washed with saturated sodium chloride solution and dried at 40° in vacuo. It dyes cotton, from a long liquor in accordance with the dyeing process indicated in Example 1, in green shades which are fast to light and wet processing.

EXAMPLE 46

9.0 g of 2-(4'-amino-2'-ureido-phenylazo)-benzene-1,4-disulphonic acid are reacted with 2.0 ml of cyanuric fluoride in the manner described in Example 45.

The resulting solution of the difluorotriazinylazo dyestuff is added, in the course of 15 minutes, to a solution of an anthraquinone dyestuff, which has been prepared by dissolving 8.0 g of 1-amino-4-(3'-amino-2'-methyl-phenylamino)-anthraquinone-2-sulphonic acid in 150 ml of water at pH 7 and cooling the solution to 0°-5°. During the dropwise addition, the pH value of the mixture is kept at 6.0-6.5 and the mixture is then stirred under the same conditions for a further 15 hours. During this time, the temperature is allowed to rise gradually to 20°, the resulting green solution is clarified with 2 g of charcoal and 2 g of kieselguhr and the dyestuff is salted out of the filtrate by adding 10% of sodium chloride. The product which has precipitated is filtered off, washed with 10% strength sodium chloride solution and dried at 40° in vacuo.

On cotton, the resulting dyestuff of the formula ##STR33## gives, from a long liquor at 40° in accordance with Example 1, strong green dyeings with good fastness to light and wet processing.

EXAMPLE 47

14.3 g of 2-(4'-amino-2'-ureido-phenylazo)-benzene-1,4-disulphonic acid in 450 ml of water are reacted with 3.2 ml of cyanuric fluoride at 0°-5° and at pH 4.2-4.7 in the manner described in Example 45. The resulting difluorotriazinylazo dyestuff solution is allowed to run into a neutralised solution of 15.1 g of 1-amino-4-(4'-methylaminophenylamino)-anthraquinone-2,2'-disulphonic acid in 150 ml of water at 0°-5° in the course of 20 minutes, and the pH value of the reaction mixture is kept at 6.0-6.3 with 1 N sodium carbonate solution. When the reaction has ended, after 2 hours, the mixture is warmed to 20° and the resulting green dyestuff is salted out with 7% of sodium chloride. It is filtered off, washed with 10% strength sodium chloride solution and dried at 40° in vacuo.

The dyestuff of the formula ##STR34## dyes cotton, from a long liquor at 40°, in yellowish-tinged green shades which are distinguished by good fastness to light and wet processing and, in particular, also fastness to chlorine.

EXAMPLE 65

10.5 g of 1-(4'-sulphophenyl)-3-carboxy-4-(5"-amino-2"-sulphophenylazo)-5-pyrazolone are dissolved, at pH 8-9, in 300 ml of water. After cooling the solution to 0°-5°, the pH value is adjusted to 4.8 and dropwise addition of 1.8 ml of cyanuric fluoride is strated immediately. The pH value is kept at 3.7-4.2 with 1 N sodium carbonate solution during the dropwise addition of the cyanuric fluoride, and the addition of the reactive component is ended within 5-10 minutes. The condensation reaction is then brought to completion in the course of 30 minutes by subsequently stirring the mixture, a pH value of 4.2 being maintained.

The resulting solution of the difluorotriazinylazo dyestuff is now added dropwise to a neutralised solution of 10.0 g of 1-amino-4-(4'-amino-phenylamino)-anthraquinone-2,2'-disulphonic acid in 200 ml of water at 0°-5° in the course of 15 minutes, and during this addition the pH value of the mixture is kept at 6.3-6.5. When the condensation reaction between the difluorotriazinylazo dyestuff and the aminoanthraquinone component has ended, after about 2 hours, the mixture is warmed to 20°, the solution is clarified with 2.5 g of charcoal and 2.5 g of kieselguhr and the resulting filtrate is salted out with sodium chloride. The resulting dyestuff is filtered off, washed with sodium chloride solution and dried at 40° in vacuo. It corresponds to the formula ##STR35## and dyes cotton, from a long liquor at 40°, in clear, yellowish-tinged green shades with good fastness to light and wet processing.

If the azo components indicated in Table IV, column II are subjected to an analogous condensation reaction with cyanuric fluoride and the resulting intermediate products are then subjected to a condensation reaction with the anthraquinone components of column III, further dyestuffs are obtained which dye cotton, from a long liquor, in the colour shades indicated.

EXAMPLE 88

9.0 g of 2-(4'-amino-2'-ureido-phenylazo)-benzene-1,4-disulphonic acid are dissolved, at pH 5.5, in 315 ml of water and the solution is cooled to 0°-5°. 2.4 ml of cyanuric fluoride are added dropwise to this solution in the course of 10 minutes, and the pH value is thus kept between 4.2 and 4.7 by adding 2 N sodium carbonate solution dropwise. In order to bring the reaction to completion, the mixture is subsequently stirred at 0°-5° and at a pH value of 4-5 for a further 30 minutes.

The resulting solution of the difluorotriazinyl-azo dyestuff is added dropwise to a solution, adjusted to pH 7 and initially warmed to 20°-25° C., of 10 g of 1-amino-4-(4'-methyl-2'-aminomethyl-anilino)-anthraquinone-2,6'-disulphonic acid in 100 ml of water in the course of 30 minutes, the pH value being kept between 6.5 and 7 by adding 2 N sodium hydroxide solution dropwise. As a result of the cold azo dyestuff solution running in, the temperature thereby falls to 15°-18°. The green solution is subsequently stirred for a further 30 minutes and the dyestuff is then salted out with 42 g of sodium chloride in the course of one hour. The dyestuff, which has crystallised out in small prisms and has, as the free acid, the following formula ##STR36## is filtered off, washed with 10% strength NaCl solution and dried at 40° in vacuo.

Printing Instructions:

A paste is prepared from 40 g of the above dyestuff, 500 g of alginate thickener, 20 g of sodium bicarbonate, 10 g of sodium nitrobenzene-3-sulphonate and 300 g of water and is then made up to 1 kg with water. A cotton fabric is printed with this paste, dried, steamed at 105° for 8 minutes, rinsed with hot water, then soaped at the boil, rinsed and dried. A green print with very good fastness properties is obtained.

EXAMPLE 89

If the anthraquinone component indicated in Example 88 is replaced by the same amount of 1-amino-4-(4'-N-Methylaminomethylanilino)-anthraquinone-2,2'-disulphonic acid and the procedure is otherwise as described, a green dyestuff which, as the free acid, corresponds to the formula ##STR37## is obtained.

It dyes cellulose fibres, in accordance with the process indicated in Example 1, in bluish-tinged green shades of very good fastness to light, wet processing and chlorine.

EXAMPLE 101

9.7 g of 1-(4'-sulphophenyl)-3-carboxy-4-(4'-amino-2'-sulphophenylazo)-5-pyrazolone in the form of the sodium salt are dissolved in 200 ml of water. The solution is adjusted to pH 6 and cooled to 0°-5°, and 1.8 ml of cyanuric fluoride are slowly added dropwise at this temperature; during this addition, the pH value is kept at 4-4.5 by simultaneously adding 20% strength sodium carbonate solution dropwise. The mixture is subsequently stirred at 0°-5° for some time.

A solution of 12.5 g of 1-isopropylamino-4-(4'-amino-phenylamino)-5-hydroxy-anthraquinone-2',6-disulphonic acid (potassium salt) in 200 ml of water is then added dropwise. The pH value is kept at 5.5 with sodium carbonate solution during the dropwise addition. The pH value is then kept at 6.0 and the temperature is allowed to rise gradually to 20°-25°. After the condensation reaction has ended, the dyestuff of the formula ##STR38## is salted out with 80 g of sodium chloride, filtered off, washed with 20% strength sodium chloride solution and made into a paste with 10 ml of a 5% strength buffer solution of pH 6. After drying the paste at 60°, a dyestuff is obtained, which dyes cotton, from a long liquor in accordance with the dyeing process of Example 1, in clear, yellowish-tinged green shades, or with which, in accordance with the process of Example 88, equivalent prints are obtained.

Similar dyestuffs are obtained when the azo components indicated in Table VI (column II) are subjected to a condensation reaction with cyanuric fluoride and the condensation product is then further reacted with the anthraquinone components of column III.

12.0 g of the trisodium salt of 2-(5'-amino-2'-sulphophenylazo)-1-hydroxy-7-(3"-sulphophenylamino)-naphthalene-3-sulphonic acid are dissolved, at pH 6, in 360 ml of water. After cooling the solution to 0°-5°, the pH value is adjusted to 5.0, and 1.8 ml of cyanuric fluoride are then added dropwise in the course of 10 minutes. The pH value is kept at 4.2-4.5 with 1 N sodium carbonate solution during the dropwise addition of the reactive component. The mixture is subsequently stirred at pH 4.5 for about 30 minutes. The resulting dark brown solution of 9.0 g of 1-amino-4-(3'-amino-2'-methyl-phenylamino)-anthraquinone-2,5'-disulphonic acid given and the pH value of the mixture is kept at 5.8-6.0 with 1 N sodium carbonate solution. After the condensation reaction between the difluorotriazinylazo dyestuff and the anthraquinone component has ended, the deep black solution is warmed to 20° and the resulting dyestuff is salted out with about 10% of sodium chloride, filtered off and washed with 10% strength sodium chloride solution. The dyestuff, which corresponds to the formula ##STR39## is dried at 40° in vacuo. Using this dyestuff, grey to black dyeings, depending on the amount of dyestuff employed, with good fastness to light and wet processing, including fastness to chlorine, are obtained on cotton, from a long liquor at 40°.

If the azo components indicated in Table VII, column II are subjected to a condensation reaction with cyanuric fluoride and the condensation products are further reacted with the anthraquinone components of column III, dyestuffs are obtained which dye cotton in the shades indicated.

EXAMPLE 159

9.8 g of 1-amino-4-(3'-amino-phenylamino)-anthraquinone-2,4'-disulphonic acid are dissolved in 150 ml of water. The solution is adjusted to pH 5 and cooled to 0°-5°, and 1.9 ml of cyanuric fluoride are then slowly added dropwise. During this addition, the pH value is kept at 4.5 with sodium carbonate solution and the mixture is subsequently stirred under these conditions for a further 15 minutes. 4.8 g of 6-amino-1-naphthol-3-sulphonic acid are dissolved, at pH 6, in 50 ml of water. The solution is added dropwise to the anthraquinone component, the pH value of the mixture is kept at 6.0 with sodium carbonate solution and the temperature is allowed to rise gradually to 20°.

When the condensation reaction has ended, the reaction mixture is cooled to 0°-5° and a diazonium salt solution which has been obtained by diazotising 3.5 g of 2-amino-benzene-sulphonic acid is then added. The pH value is kept at 6.5-7 for the coupling reaction and, after the diazonium salt has been added, the temperature is allowed to rise gradually to 20°. After the coupling reaction has ended, the dyestuff is salted out with 50 g of sodium chloride, filtered off and washed with 10% strength sodium chloride solution, and the product is made into a paste with 10 ml of a 5% strength buffer solution which has a pH value of 6. After drying the paste at 60°, a product is obtained which corresponds to the formula ##STR41## and dyes cotton, in accordance with the dyeing process of Example 1, in brownish-tinged olive shades.

EXAMPLE 160

14.7 g of 1-amino-4-(4'-amino-phenylamino)-anthraquinone-2,3'-disulphonic acid are dissolved, by neutralisation, in 300 ml of water. After cooling the solution to 0°-5° and adjusting the pH value to 4.5, 2.7 ml of cyanuric fluoride are added dropwise in the course of 10 minutes, and the pH value of the solution is kept at 4.2-4.5 by means of 2 N sodium carbonate solution. The reaction has ended a few minutes after the dropwise addition. A solution, adjusted to pH 6, of 7.2 g of 6-amino-1-naphthol-3-sulphonic acid in 100 ml of water is then added to the anthraquinone component and the pH value is kept at 5.8-6.2 with sodium carbonate solution and the temperature is further kept at 0°-5°, for the purpose of the condensation reaction.

When the condensation reaction has ended, a diazonium salt solution which has been prepared by diazotising 7.6 g of 2-aminobenzo-1,4-disulphonic acid in 100 ml of water and 20 ml of concentrated hydrochloric acid with 2.1 g of sodium nitrite at 0°-5° is added to the greenish-tinged blue dyestuff solution.

The pH value of the mixture is kept at 5-6, and the mixture is subsequently stirred until the coupling reaction has ended. The dyestuff is salted out of the brown solution at 20° with 20% of sodium chloride. The precipitate is filtered off and washed with 20% strength sodium chloride solution, and the product of the formula ##STR42## is dried at 40° in vacuo. The dyestuff dyes cotton, from a long liquor in accordance with the dyeing process of Example 1, in brownish-tinged olive shades. The dyeings have very good fastness to light and wet processing.

Further dyestuffs can be obtained analogously when the anthraquinone components listed in Table IX, column II are subjected to a condensation reaction with cyanuric fluoride, the products are then subjected to a condensation reaction with the coupling components of column III, and finally the diazonium salts of the amines from column IV are coupled to the condensation products.

EXAMPLE 181

9.8 g of 1-amino-4-(3'-amino-phenylamino)-anthraquinone-2,4'-disulphonic acid are dissolved in 200 ml of water and subjected to a condensation reaction with 1.9 ml of cyanuric fluoride, which is added dropwise, at 0°-5° and at pH 4.5. After subsequently stirring the mixture for a short time, a neutral solution of 9.8 g of the copper complex of 6-amino-2-(2'-hydroxy-5'-sulpho-phenylazo)-1-naphthol-3-sulphonic acid in 150 ml of water is then added and the reaction mixture is adjusted to 6.0 with 20% strength sodium carbonate solution. The temperature is allowed to rise to 20°, the pH value being further kept at pH 6. When the reaction has ended, after several hours, the dyestuff of the formula ##STR47## is salted out with 60 g of sodium chloride, the precipitate is filtered off, the filter cake is washed with 15% strength sodium chloride solution and the product is dried at 40° in vacuo. The dyestuff dyes cotton, from a long liquor, in strong, violet shades and, when used for printing in accordance with the process of Example 88, gives prints which are also violet.
